What are the instructions for performing the construction, as described in the 'КАК ДЕЛАЕМ' section?

How to Perform the Construction:

• С помощью линейки строим прямую l, C ∈ l; (Using a ruler, construct line l, with point C on l.)
• Ножку циркуля ставим в точку C и строим дугу с радиусом, равным AB. (Place the compass point on C and draw an arc with a radius equal to AB.)
• Пересечение дуги с прямой l — получаем точку D. (The intersection of the arc with line l gives point D.)
